Searchblog reader Adam asked me:
1) “Given a list of search terms, can Google produce a list of people
who searched for that term, identified by IP address and/or Google
cookie value?”
2) “Given an IP address or Google cookie value, can Google produce a
list of the terms searched by the user of that IP address or cookie
value?”
I put these to Google. To its credit, it rapidly replied that the answer in both cases is “yes.” Just FYI.
All I will add is this: If you are an agent of the US Government charged with tracking domestic terrorism, might you have an interest in answering questions like the ones posed above?
As the Chinese curse goes (oh, the irony), may we live in interesting times.
